Which of the following is the source of fibre ??

Egg
Milk
Wheat

Correct Answer

A. Wheat

Explanation

Wheat is the correct answer because it is a good source of dietary fiber. Fiber is a type of carbohydrate that cannot be digested by the body, but it plays a crucial role in maintaining a healthy digestive system. It adds bulk to the stool, promotes regular bowel movements, and helps prevent constipation. Wheat, especially whole wheat, is rich in fiber and is commonly consumed in the form of bread, pasta, and cereals. It is recommended to include fiber in the diet for overall health and to reduce the risk of various diseases such as heart disease, diabetes, and certain types of cancer.

Which of the following is a source of quick energy ?

Protein
Minerals
Carbohydrates

Correct Answer

A. Carbohydrates

Explanation

Carbohydrates are a source of quick energy because they are easily broken down into glucose, which is the body's preferred source of fuel. When carbohydrates are consumed, they are quickly digested and absorbed into the bloodstream, providing a rapid source of energy for the body's cells. This is particularly important during activities that require immediate energy, such as high-intensity exercise or mental exertion. Protein and minerals, on the other hand, are not typically used as a direct source of energy but have other important functions in the body.

Fish is a -----------------

Warm-blooded
Cold-blooded

Correct Answer

A. Cold-blooded

Explanation

Fish are cold-blooded animals, meaning that their body temperature is determined by the temperature of their environment. Unlike warm-blooded animals, such as mammals and birds, fish do not have the ability to regulate their internal body temperature. Instead, their body temperature fluctuates with the temperature of the water they live in. This adaptation allows fish to survive in a wide range of aquatic environments, as they can adjust their metabolism and activity levels according to the temperature of their surroundings.
